Embodiments of the present invention disclose a radio frame transmission method, including: determining radio frame configuration information, and performing uplink transmission of a radio frame according to the radio frame configuration information, where the radio frame includes at least three special subframes. Correspondingly, the embodiments of the present invention also disclose a wireless network device. With the present invention, a quantity of subframes used for uplink transmission can be increased in the radio frame. Further, a quantity of subframes used for sounding signal sending is increased, and obtaining of a downlink channel state becomes timelier.
